Description matt whiteley 2008-05-30 22:03:57 UTC 
Description of problem:
The amd automounter from the package am-utils stops working after an update to rhel 5.2. The am-
utils package itself is not updated, so there must be an incompatability with another rpm that was 
updated. The service will start and run, although it will not stop normally and the /usr/sbin/amd 
process must be killed with SIGKILL. The processes that are forked for each mount attempt segfault and 
no mounts ever succeed.


Version-Release number of selected component (if applicable):
6.1.5-4.1.el5

How reproducible:
100% in my tests of 8 boxes

Steps to Reproduce:
1.Install rhel 5.1 and configure am-utils
2.Update to rhel 5.2
  
Actual results:
All mounts fail

Expected results:
Automounting is unaffected from upgrade

It appears that this only happens when the map contains netgrpd selectors. The machines have no trouble 
looking up netgroups though. Removing the netgrpd selectors made the mounts work again. We would 
like to be able to use those though. If there is any insight as to why this broke from upgrading unrelated 
packages that would be helpful.

Matt, is this problem still reproducible with RHEL5.5?

I have taken on am-utils maintenance and noticed this bug but it is
very old.

If we are to make headway I will need some information to duplicate
the issue. In particular an example of your am-utils configuration.

Assuming of course this wasn't just a problem that has gone away
since.

Matt, can you get back to me please.
